May 17, 1949. v J. B. DANGELO NOZZLE Filed Feb. 14, 1946 JOSzF/W/B. 054 N651 Q Patented May 17, 1949 UNITED STATES PATENT OFFICE NOZZLE Joseph B. DAngelo, Tiifin, Ohio Application February 14, 1946, Serial No. 647,498

1 Claim. 1

This invention relates to nozzles and more particularly to a syringe nozzle and the primary object thereof is to provide an improved device of this character which is so constructed as to supply a medicated fluid, usually water, over and into any affected parts of the body.

Another object of this invention is to provide a syringe nozzle with means whereby a medicant or other similar substance may be readil inserted into the head portion of the nozzle Whereby when fluid is forced through the nozzle, it will mix with the aforementioned medicant to supply a medicated fluid to the affected parts of the body.

Another object of the invention is to so construct a syringe nozzle as will provide for quick and easy disconnection of the parts thereof whereupon a new supply of medicant can be placed within the head portion of the syringe nozzle and also to provide means whereby the various parts forming the syringe nozzle may be readily disconnected for loading, inspection or cleaning with facility.

A still further object of the invention is to so construct a syringe nozzle in such a manner that streams of fluid emitted from the nozzle will be directed both forwardly and rearwardly of the head portion of the syringe nozzle when it is used internally.

Other objects of the invention will become more apparent as the invention is more fully set forth in detail in the following specification and. shown in the accompanying drawing, in which:

Figure 1 is a side elevation view of the syringe nozzle embodying my invention,

Figure 2 is a central vertical longitudinal section showing on an enlarged scale the syringe nozzle embodying my invention,

Figure 3 is a fragmentary view of the forward portion of the nozzle.

Figure 4 is a sectional view of the removable head portion of my improved syringe nozzle, and

Figures 5, 6 and '7 are transverse vertical sectional views taken on lines 5-5, 66 and Il, respectively, of Figure 2.

Referring now to the drawings wherein like reference characters denote corresponding parts throughout the several views, the syringe nozzle comprises a barrel I which is made of any suitable material such as hard rubber, plastic or other similar hard substance. However, if it is desired to have a certain amount of resiliency in this portion of the syringe nozzle, the barrel I could be constructed of some flexible material such as soft rubber having suificient stiffness to permit ready insertion of the nozzle within a body cavity.

A central bore 2 extends from the rear portion of the barrel member I to the forward portion thereof where it terminates in an enlarged mixing chamber generally located by numeral 3 in the drawing. Mixing chamber 3 is formed in the front end portion of the barrel I and is provided with a plurality of openings i slanted rearwardly thereof for a purpose to be more fully described hereinafter. As clearly shown in Figures 2 and 3 of the drawing, the mixing chamber 3 is formed within the slightly enlarged portion 6 of the nozzle which is internally threaded as shown at I and engages the reduced externally threaded portion 8 of the head portion 5 of the nozzle. The head portion 5 of the nozzle comprises a tubular member having a cylindrical bore 9 extending from the rear portion thereof to a point adjacent the front portion of the nozzle where it communicates with a series of openings I0 and II formed in the tip portion I2 of the nozzle.

Tip portion I2 comprises a tubular member formed integral with head portion 5. The head portion 5 of the nozzle can be molded of hard rubber'or similar substance with openings I0 and II formed therein during the molding process or openings Ill and II can be formed therein as by drilling or boring these openings in the head portion of the nozzle 5. Openings I0 and II thus positioned in this portion of the head member 5 will direct streams of fluid forwardly of the nozzle when the device is in use.

Means are provided in the syringe nozzle for medicating the water or other fluid as it passes through the syringe nozzle and this means preferably comprises a soluble cake or cartridge I3 of medicinal material disposed within the cylindrical bore 9 of head portion 5 of the nozzle. Since the best results for medicating the fluid passing through the syringe nozzle are obtained when the soluble cake or cartridge is contained or disposed within the cylindrical bore 9 of the head member 5, the cake or cartridge should preferably be circular in form and of such a diameter as to permit easy insertion and. withdrawal thereof from within the aforementioned bore 9.

The outer surface of head portion 5 is wellrounded and tapers slightly toward the front portion thereof which is reduced to form a small tip I2 in order to permit easy insertion of the syringe within a body cavity when it is desired to use the device as a douche apparatus.

A nipple I 4 is formed on the rear portion of the barrel l to which tubing I5 is connected in any well-known manner. Tubing l5 leads to a suitable fluid supply or fluid reservoir.

In use, a suitable medicant is placed within the cylindrical bore portion of the nozzle. The head portion-5 is then threaded into the enlarged portion 6 of the barrel land the fluid supply tubing I5 is connected to the Opposite end of the aforementioned barrel. When this has been accomplished, the tubing I5 is connected to a suitable source of fluid supply and the nozzle inserted into a body cavity if it is to be used as a douche apparatus and fluid is forced through the nozzle totreat the affected parts. Since the medicant I3 is located at a point materially in the rear of the discharge orifices or openings lll f'and H, the entire stream of fluid passingthr'ough the barrel 1 will be impregnated and 'permea-tedwith and bythemedicant to such an extentthat the whole stream "of fluid passing through the syringe nozzle is rendered medicinal. The medicant placed within the cylinder borefl will; to some extent, retard the fiowof fluid-"through orifices or openings l0 and ll"'form'ed "in"the front portion of head memberS-With the, result" that-"streams of medicated *cfluid willbe dir'ec'ted -rearwardly of the; head portion-of the nozzle-through open 'ings; 4 provided rin-mixingphamber 3.

It is, of course,-apparent" that the medicant maybe omittedrentirely fromthe head portion ofthesyringe nozzle thereby permitting the free flow of water or-other fluid through the openings 4,;l0and when-it is desired to supply an unmedicatedwater or-other fiuidto the affected parts. Likewise; it'- of-'cou rse, obvious that 'instea'dofZusingamedicant in this portion of the nozzle,-an ganesthetic orantis'eptic could likewise be-placedain this portio'n: of the syringe nozzle and the device'usedfor various other purposes.

While a preferred specific embodiment of the invention is hereinbefore set forth, it is to be clearlyunderstoodthatl' amnot'to be limited to the exact"'fconstructioniillustrated and described, because various modifications of these details .may be' resorted to putting the invention into practice within the purview of the appended claim.

I claim:

A syringe nozzle comprising a tubular barrel open at front and rear ends and having its rear end adapted for engagement with a fluid-supply tube, the front end portion of said barrel being of increased diameter and formed internally with a mixing chamber of greater diameter than the bore of said barrel and having an annular wall threaded from its front end, there being outlet openings extending radially from the rear end of the mixing chamber at a rearward incline through the annular wall thereof and spaced from each other circumferentially thereof, a head having anexternally threaded neck at its rear end screwed into the mixing chamber of said barrel, said head being tapered towards its front end and having its front end portion reduced in diameter to form a tip, said head having a longitudinally extending pocket of less diameter than the mixing chamber forming a continuation of the mixing chamber at a. rearward incline said head being formedwith a centrally located outlet opening extending from thepocket through the tip longitudinally thereof andlwith other outlet openings surrounding the .central outlet opening and extending fromf the pocket through side portions of the tip'finf spaced relation to each other circumferentially thereofland an elongated medicant cartridge. fitting loosely inthepocket of said head with its rear. portion-extending iiito the mixing chamber and its front endretarding free flow of fluid through the outlet openings of the head.
